Benefits of technology

The patent describes a cardiac rhythm management system that can detect a heart attack and adjust its pacing algorithm accordingly. The system includes an implantable device with sensing and pacing capabilities, as well as an external system for controlling the device. The system can automatically adjust pacing parameters based on the patient's activity level and deliver pacing pulses to improve heart function. The technical effect of this invention is to provide better heart function and control over the pacing algorithm after a heart attack.

Problems solved by technology

A blocked or otherwise abnormal electrical conduction and / or deteriorated myocardial tissue cause dysynchronous contraction of the heart, resulting in poor hemodynamic performance, including a diminished blood supply to the heart and the rest of the body.

Abstract

A cardiac rhythm management system includes an implantable device executing a dynamic pacing algorithm after an myocardial infarction (MI) event. The dynamic pacing algorithm dynamically adjusts one or more pacing parameters based on a person's gross physical activity level. Examples of the one or more pacing parameters include atrioventricular pacing delays and pacing channels / sites. The dynamic pacing algorithm provides for improved hemodynamic performance when a person's metabolic need is high, and post MI remodeling control when the person's metabolic need is low.
